The control of turbulent flows around bluff bodies by means of spanwise sinusoidal profiles
Bluff bodies form ubiquitous components of many engineered structures. They are often exposed to turbulent flows, and the subsequent shedding of vortices gives rise to aerodynamic forces with large fluctuating components. As a result, significant oscillations are induced, which can lead to …

Heat transfer and condensation of water vapour from humid air in compact heat exchangers
In this thesis, an experimental and simulation study of heat transfer in water-to-air compact-plate heat exchanger is presented. A compact-plate heat exchanger made of polypropylene, in which flow pattern is maintained as counter-current, was constructed to conduct the experiments. Experiments were …

Granular sloshing absorbers for vibration control
Tall, flexible structures may be exposed to excessive oscillations when subjected to wind, earthquakes or other shocks. Passive and active absorbers are employed, often at great expense, to stabilise the structures for the safety and comfort of the occupants. Current passive damper technologies …

Similarity in adverse pressure gradient turbulent flows
The purpose of this research is to experimentally generate increasingly adverse pressure gradient flow data for comparison with published data, to find similarities allowing categorization leading to improved flow prediction.

Interaction between turbulent flow and saturated porous media
In this thesis, the interaction between turbulent flow and saturated porous media has been investigated using computational fluid dynamics (CFD) simulations, flow visualisation experiments and laser Doppler velocimetry (LDV) measurements.
